To all whom it may concern:

Be it lmown that I, KARL EDISON, a subject of. the Emperor-of Germany, residing at Manhattan borough, county, city, and State useful Improvements in Electric Lamps, of

which'the following is a full,'clear, and exact description. g

This invention relates to an improvement in electric lamps, the object bein to provide a lamp of this character that w' I throw the rays of light a great distance by means of a specially arran ed reflector. To carry out the principle 0 my invention, I preferably employ a rotatable globe adjacent to which I place areflector that is adapted to be moved toward and away from the said globe alternately, whereby the meant the reflected body of light is increased and decreased. Further features of my improyed lamp will be hereinafter set forth.

I will now proceed to describe my improved lamp in detail, the novel'features of which will be set forth in the claims, reference being had to the accompanying drawreferred embodi- V ings, which illustrate a ment of my inventlon, w erem:

Figure 1 illustrates a side view of my 1mproved lamp, partly in section; Fig.2is an enlarged front view of the reflector ywhich forms part of my invention; and Fig. 3* is an enlarged sectional plan view taken on a line 3-3 in Fig. 1, showing the reflector moving device, the cap of the ball-joint being removed. a

My improved lamp as herein illustrated comprises al hollow base-portion -1, su port ing a motor 2, in this instance, an e ectric" motor, the said motor being provided with a shaft 3, carrying a pinion 4, which meshes with and rotates a gear 5 secured 'to the lower end'of the Vertically disposed rotatable shaft 6. To the upper end of the shaft 6, I secure a pinion 7 meshing with and operating a gear8, carried. by a sleeve 9 rotatably mounted on a stationary tubular support 10. The tubular support 10 is secured to the base-portion 1 in an desirable manner and has. secured thereto stance) an ornamental s here 11 carrying a bearing bracket 12 for t e shaft 6. To the tubular support 10, I also secure a bracket 13, having pivotally connected thereto, as at 14, an arm 15, to the outer end of which is secured the reflecting ,device16. Interme- In order that the rays of lig in this in-;

diato the ends of the arm 15 I mount a post 17 provided at its upper end with a socket member 18 of a ball-and-socket joint. ball member of the joint is indicated by 19 of New York, have invented certain new and 1 The (Fig. 3) and, iscarried on the outer end of an arm 20, which at itsv inner end is pro- 19 is retained in the socket 18 by a cap 23- 'which may be secured to the socket by' screws.

The illuminating medium as. herein illustrated comprises an ordinary bulb-light 24:, which is carried by a socket 25 on the upper end of the tubular support 10. The 1i ht located within a globe 26, prefera hly ofmetal or some other 0 aquesubstance.

A lt from the bulb 24 can be thrown upon the reflector,-I place in the wall of the globe 26 a plurality of transparent members 27 preferably of glass. The transparent members 27 may all be of the same color or of diflerent colors. The reflector which I employ is of a conical formation, as shown, and consists of a body portion 28, having secured thereto at its central portion an opaque plate 29, the remain-- der of the inner surface of the body portion 28 being covered by reflecting elements 30 (see Fig. 2). y

As can be seen in Fig.2, the globe 26, which is indicated by dotted lines, is centrally located with respect to the reflector 1.6; consequently the opaque disk 29-will intercept the rays of light which penetrate or pass through those transparent members 27 which come in alinement therewith as the globe 26 rotates. For instance, by referring to Fig. 1, it will be seen that the row 31 of the transparent members 27 is directly in line with the opaque plate 29, and consequently as the. globe 26 rotates, the rays of ratemeaaaaraiaia Application filed May 18,1911. Seria1'No.627,928.,"

light which pass through the members in from the globe the size of the reflected globe will ap ear'to alternately increase and decrease dbe to the changing of the focus of the reflecting bodies.

i When colored transparent bodies are used in the globe a very beautiful eflect is produced. By the alternate increasing and decreasing of the area of the reflected light by moving the reflector, the light can be seen from a great distance.

As the motor rotates, the globe 26 will be rotated and the reflector oscillated on its pivot by the eccentric 22.

Having now described my invention, what I claim and desire to secure by Letters Patent is:

1. A lamp comprising a rotatable globe, means for rotating said globe, a lurality of transparent bodies in the wall 0 said globe, a reflector mounted adjacent said globe, means for moving said reflector toward and away from said globe, and an illuminating medium in said globe.

2. A lamp comprising a rotatable globe, an illuminating medium within said lobe, a reflector mounted adjacent saidl glo e and adapted for an oscillating movement, and

means for rotating said globe and oscillating said reflector simultaneously.'

3. A lamp comprising a support, a rotatable shaft mounted on said support, a globe rotated by said shaft, an illuminating medium'within said globe, a reflector adaptedv for movement toward and away from said globe, an eccentric carried by said shaft adapted to operate sald reflector, and means for rotating said shaft.
